Outcomes and validity of risk stratification tools for endoscopic submucosal dissection of early gastric cancer in Western Australia.

Background And Aim: Endoscopic submucosal dissection (ESD) has become the treatment of choice for many superficial gastric neoplasms. Clinical outcomes are increasingly comparable between Japanese and Western series; however, data are lacking on the validity of risk stratification tools in Western cohorts. We aimed to evaluate clinical outcomes, explore risk stratification, and compare our data with published Western series.
